DIPPING-CAR.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed October 30, 1907. Serial No. 399,852.

To all whom it may concern:

Be it known that I, JOHN E. CARLSON, a citizen of the United States, residing at Vermilion, in the county of Clay, State of South Dakota, have invented certain new and useful Improvements in Dipping-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the Same.

This invention relates to apparatus for dipping cattle.

At the present time, a dipping board is employed and the cattle are driven onto the oard and when they reach the outer end, are

tripped into the dip ing tank. While this process seems feasi le enough, it is well known to those skilled in the art that considerable difliculty is experienced in getting the cattle to walk along the board to the pro er point as the board is so balanced that it egins to tip frequently before the cattle are at the roper point and in time for them to turn bac i. After this happens, it is a difficult matter to make them walk along the board again.

My invention has for its object to provide a dipping car upon which the cattle stand and are carried toward the tank, the car being so constructed that when the end of the track is reached, the car platform will quickly tilt and throw them into the dipping tank.

l -In the accompanying drawings, Figure l is a side elevation of the ap aratus in use, Fig. 2 is a similar view with t e car at the end of the track and tilted, Fig. 3 is a top plan view, Fig. 4 is a vertical longitudinal sectional view, Fig. 5 is a detail side elevation of the rear end of the car showing the mechanism for closing the end gate thereof, Fig. 6 is a detail rear end view of the car.

In the drawings the car is shown as comprising a bed frame which is made up of side sills 10, end sills 11, and braces 12 which brace the side sills. The car bed frame is supported for travel at its forward and rear ends by means of axles 13 and 14 and wheels 15 and 16 respectively. The car also com prises a trip board 17 which extends at its rear half, the entire length of the car and has its front half projecting beyond the front end of the car to adistance equal to or more than the length of the car, the said trip board being ivoted as at 18, adjacent its middle, to the ont end sill 11.

The wheels 15` and 16 of the car travel upon tracks 19 which are 'inclined and which lead to a point adjacent the edge of the dipping tank into which the animal is to be plunged, and the extreme 'forward end of the car is normally supported by means of wheels 20 which are located at the forward end ofthe trip platform or board and travel upon tracks 21 which run above the tracks 19 for nearly their entire length and forwardly beyond the same and to the edge of the dipping tank.

A bumper 22 is located at the forward end of the tracks 19 and it will be understood that when the animal has been driven onto the trip platformand the car started down the inclined tracks 19, the front wheels 15 will strike the bumpers and the car be sud-.

denly stopped, At this time, the wheels 20 will ride over the front ends of the tracks 21 and the platform will be permitted to tilt and throw the animal into the tank.

In connection with the car, I have provided an end gate and a lever for closing the end gate and at the same time releasing the car and permitting it to descend the tracks provided for its support and this mechanism will now be described.

The numeral 23 denotes an end gate to the end edges of which are secured irons 24 the iron upon one end edge of the gate being pro vided with a forwardly and right angularly extending arm 25 at its right end. rI`he end gate is pivoted for swinging movement to the rear end of the tilting platform of the car by means of bolts 26 which are passed through the said irons 24 at their lower ends and secured u on the end gate at the said end edge thereof 1s a lever 27 which serves as a means whereby the end gate may be raised to upright position. A lug 28 having an abrupt forwardly presented face 29 is fixed upon the under side of the said tilting platform of the car at that side thereof at which the arm 25 is located and pivoted upon asuitable support 30 arranged beside the corresponding one of the main track rails for the car is a latch arm 31 which is extended rearwardly and up wardly and abuts at its rear end against the said abrupt face 29 of the lug when the car is at its standstill at the upper or rear end of the track, the car being 1n this manner held against movement. A spring 32 is disposed upon the support and bears at its upper end against the upper side of the rear en of the latch arm 31 and serves to normallyhold it in raised position for such engagement with said lug.

In order to start the car, or in other words to release it and permit of its travel down an inclined track, it is only necessary to graspl the lever 27 and swing it upwardly at the same time raising the end gate. It is essential that the lever be moved Yforwardly past the vertical plane so that the end o f the arm 25 will ride against the latch arm 31 and release the same from engagement with the lug 28 thereby releasing the car. The lever is limited in its forward movement by means of a stop pin 33 formed integral with a plate 34 which is secured upon the upper face of the platform of the car at the said side thereof. It is essential that some means be provided whereby the end gate may be held in raised position after having been so moved and to this end l have provided upon the support 30, a curved abutment 35 with which cooperates a trip 36 having a curved under edge 37, this trip being pivoted as at 38 upon the said side edge of the car platform. The trip comprises also a finger portion 39 to which is attached the lower end of a spring 40, the said spring being secured at its upper end to a pin 41 projecting from a plate 42 secured upon the said platform. This spring tends to normally raise the finger end 39 of the trip 36 this movement being limited by a stop pin 43.- The curved under edge of the trip 36 is designed to ride over the convex upper edge or surface of the abutment 35 as will be readily understood and the rear end of the finger 39 projects in the path of movement of the forward end of the arm 25 and when the lever 27 is operated to swing this arm forwardly past a vertical plane, the said finger end of the trip will be depressed and the forward end of the arm 25 engaged i therebeneath it being understood that this occurs after the trip has passed the abutment 35. From the foregoing it will be understood that the finger end 39 of the trip 36, by reason of its engagement with the pin 43 and above the forward end of the arm 25, will hold the end gate against rearward movement or opening, the finger 33 preventing its forward movement to any considerable eX- tent.

Upon return ofthe car to the upper end of the track, the convex under edge 37 of the trip will ride over the abutment 35 and the finger end of the trip will be de ressed and disengaged from the forward en of the arm 25, this disengagement serving to release the end gate and permit of its dropping to open position. This operation is automatic.

In order that the car may be returned to the up er end of the track after the animals have een discharged from the platform thereof, a pair of cables 44 are connected to the rear end of the frame of the car and are extended rearwardly, beneath pulleys 45 upon uprights 46 vertically and over pulleys 47 at the upper ends of the said uprights and thence downwardly they being connected at their lower ends with suitable weights 48 which are of sufficient size to automatically retract the car.

What is claimed, is-- l. In a mechanism of the class described, the combination with car supporting tracks and trip tracks, of a car comprising a bed frame, wheels su porting the frame and arranged for trave upon the car supporting tracks, a platform pivoted upon the car for tilting movement, and wheels carried at one end of the platform and arranged for travel upon the tri tracks, the said wheels being arranged to eave the trip tracks when the car has reached the forward limit lof its movement along the car supporting tracks and thereby permit tilting of the platform.

2. In a mechanism of the class described, the combination with car supporting tracks, and trip tracks, of a car arranged for travel upon the car supporting tracks, a platform tiltably mounted upon the car, and wheels carried at one end of the platform and arranged for travel upon the trip tracks and to leave the same when the car has reached one limit of its movement upon the car supporting tracks.

3. A mechanism of the class described comprising a car, an inclined track upon which the car travels, means for returning the car from the lower end of the trackto the upper end thereof, a platform tiltably supported upon the car, and means for supporting the platform against such tilting movement until the car has reached the lower limit of its movement.

4. A dipping car of the class described comprisinga frame, a platform tiltably supported upon the frame, an inclined track upon which the frame travels, inclined trip tracks by which the platform is supported against tilting movement, said tracks terminating at such point as to permit of tilting of the platform when the car has reached the lower limit of its movement, and means for holding the car at the upper limit of its movement, said means comprising a lug upon the under side of the car, a latch arm arranged in operative relation to said lug, and a lever movable to disengage said latch arm from such lug.

5. A dipping car of the class described comprising a frame, a platform tiltably supported upon the frame, an inclined track upon which the frame travels, inclined trip tracks by which the platform is supported against tilting movement, said tracks terminating at such point as to permit of tilting of the latform when the car has reached the lower imit of its movement, and means for holding the car at the upper limit of its movement, said means comprising a lug seance ported upon the frame, an inclined track upon which the frame travels, inclined trip tracks by which the platform is supported against tilting movement, said tracks terminating at such point as to permit of tilting of the platform when the car has reached the lower limit of its movement, and means for holding the car at the upper llmit of its movement, said means comprising a lug upon the under side of the car, a latch arm arranged in o erative relation to said lug, a lever movablle to disengage said latch arm from said lug, a vertically movable end gate supporting the lever, a trip arranged to hold said end gate raised, and an abutment arranged in operative relation to the Itrip to actuate thesame when the car is returned to the upper end of the track whereby the end gate Will be released.

In testimony whereof, I affix my signature, in presence of two Witnesses.
